MULTIPLE DRYER VENT
INSTALLATION
A main exhaust vent can be used for exhaust-
ing a group of dryers. The main exhaust vent
should be sized to remove 200 CFM of air per
dryer.
Large-capacity lint screens of proper design
may be used in the main exhaust vent if checked
and cleaned frequently.
The room where the dryers are located should
have makeup air equal to or greater than the
CFM of all the dryers in the room.
An exhaust hood should cap the exhaust vent
to prevent exhausted air from returning into the
dryer. The outlet of the hood must be at least
12
″
(30.5 cm) from the ground or anything else
that may restrict flow of exhaust air. If an
exhaust hood cannot be used, the outside end
of the main vent should have a sweep elbow
directed downward.
A Back-draft Damper Kit, # 3391910 , is avail-
able from your Whirlpool dealer and should be
installed in each dryer's exhaust vent to pre-
vent exhausted air from returning into the dry-
ers, and to keep individual exhausts in balance
within the main exhaust vent. Unobstructed air
openings are required.
Each exhaust vent should enter the main vent
at an angle pointing in the direction of the
airflow.
Vents entering from the opposite side should
be staggered to reduce the exhausted air from
interfering with the other vents. The maximum
angle of each vent entering the main vent
should be no more than 30 degrees. Keep air
openings free of dry cleaning fluid fumes. Fumes
create acids which, when drawn through the
dryer heating units, can damage dryers and
loads being dried. A clean-out cover should be
located on the main exhaust vent for periodic
cleaning of the exhaust system.
